To all whom t may concern:

Be it known that I, FRANKLIN G. HOBART, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wiscousin, have invented certain new and useful Improvements in Gas-Purifiers, of which the following is a specification, reference being had therein to the accompanying drawings. My invention relates to new and useful improvements in puriiiers or filters for gases or liquids; and it consists in the 'construction and arrangement of parts thereof as will be more fully hereinafter described, and set forth in the claims. v

The object of my invention is to construct a purifier or filter which can be adapted for use, having a wide range of capacities, which' will be simple to construct and convenient for cleaning and which presents a large surface of purifying or filtering material to the passage of the gas.

In the drawings, Figure 1 is a vertical central section through the purifier. Fig. 2 is a plan view of the end of the purifier.

1 represents a shell or chamber, preferablyV a metallic cylinder, on which are the to 2 and the bottom 3 of greater diameter t an the shell and having the annular iianges 4 and 5 tightly surrounding the ends of the shell. In the top 2 are the inlet-opening 6 and the youtlet-opening 7, at which the uriier may be connected ,at any point o the system of a gas-producer. Inside the shell are two approximately vertical pipes or conduits 8 and y9, registering with the inlet and outlet openings, respectively, and extending frointhe top to the bottom. AThese conduits l preferably build up in sections, as I will hereinafter describe; but it is obvious lthat they may be formed integrallv, if desired. The interior of the shell is divided into a plurality of compartments by the transverse horizontal partitions 10. I have shown a shell divided into three compartments but it is obvious that more divisions may be made, necessitating merely a shell of greater height, when it is desired to increase the capacity of the purifier. In each compartment is one or more trays 11, on which the purifying or filtering material may be placed. I have shown two trays in eachcompartment; but any number may be used to secure the degree of pu- Y rity desired.` In the inlet-conduit near the upper end of each compartment are the openings 12 12, through which the gas or liquid passes into the compartment, and in the outlet-conduit near the lower end of each compartment are the openings 13 13, through which the gas or liquid may escape into the outlet-passage. The trays 11 closely fit the interior of the shell and around the conduits, and they are placed intermediate the openings in the inlet and outlet conduits, whereby the fluid entering the compartment must pass through the material on the trays before it can escape into the outletconduit- An opening 14 is provided immediately above each tray, through which the iiltering material can be examined and renewed, if neces-,

sar and an opening 15 is provided above eac partition, through which inspection may be made. .l

As above stated, I preferably form the inlet and outlet conduits of separate tubes extending between each two adjacent partitions, as clearly shown in Fig. 1, each tube having an inwardly-extending flange 16 at each end to increase its bearing-surface. Between each two pairs of these tubes are the metallic collars 17 17 for su porting the partitions. If desired, these collars may be fixed to the partitions. A

A pair of lugs 18 are attached to the bottom of the shell by any suitable means, and to these are attached the rods 19, passing the length of the conduit and terminating with threaded ends 20 outside of the inlet and outlet connections, as shown in the drawings, and adapted to engage the nuts 21. By these rodsthe assembled parts are clamped tightly together j but it is obvious that the parts may be riveted or clamped in 'any other way Without departing from the scope of my invention. y

The trays rest upon supports 22, the supports for the upper tray. resting` on the lower tray. T have shown these supports formed angled and grouped around the conduit; but they may be in the form of rings fitting loosely around the conduits. They may be of any desired form without departing from the scope of my invention.

l also nd it desirable to provide in the lower end of the inlet-conduit an opening 23, having a removable plate 24 and a handrhole 25 in the shell having the removable cover ICO IOS'

` conduit may be readily removed.

In order to make each compartment gastight, I preferably calk the edges of the partitions With rope of any desired calking material, as shown at 27 in the drawings.

What I claim, and desire to secure by Leti ters Patent, is-

1. In a urifier for gas or liqluid, the combination wlth a shell, of a plura ity of removable trays bearing filtering material supported thereirr and a pair of parallel conduits passing snuglyI through apertures in said trays, one of said conduits having inlet-ports on one side of the trays, the other conduit having outlet-ports on the other side of the trays, for the urpose described.

2. In a uri er for gas or li uid, the combination wlth a shell, of a plura ity of removable partitions 'frmin a lurality of. compartments therein, a p uraiity of removable trays bearing filtering material su ported in each compartment, a pair of con uits passing the length of the shell and each formed of a lurality of complementary sections having in et and outlet ports, substantially as described.

3. `In a purifier for gas or liquid, the combination with a casing, of a bottom therefor, a plurality of partitions, a plurality of trays bearing filtering material, linlet and outlet conduits, and a closure for the top of the casing, said partitions, trays and conduits being adapted to be inserted through the end of said casing.

4. In a purifier for gas or liquid, the combination with a casing havin a bottom, of a plurality of removable trays earing filtering material supported in said casing, and a pair of ported conduits resting on said bottom and passing through said trays, substantially as described.

5. In a purifier for gas or liquid, the combination with a casing having a bottom, of a plurality of removab e partitions 'closely fitting the interior of said easing formin com-V partments therein, trays bearing tering material supported in said compartments, an apertured closure for the top of the casing, and a pair of sectional conduits extending from the bottom of said casing into registration'with the apertures in said closure, each section being ported and extending substantially the length of a compartment, substantially'as described.

In testimony whereof I affix my signature in presence of two Witnesses.
